An entrepreneur named Kevin Halpern maintains that the chief executive officer (CEO) of Uber, Travis Kalanick, and co-founder Garrett Camp, stole the idea of ??creating a private car transport service.

Halpern, who filed a complaint in a San Francisco court, said he shared the details of the company that he was developing with Kalanick when both were working in nearby offices, in 2006.

“Kalanick was very good winning my confidence,” Halpern said in a video, posted on YouTube in which he explains the alleged appropriation of his idea. Halpern says he and Kalanick discussed “the huge business opportunity in the market of private transport, and he had no idea at the time”.
